My first brew with the Brewpi.
I am able to cool the wort to no lower than around 29-30 degrees (Celcius) using a counter flow chiller, but wish to ferment at around 19 degrees.
I am using Safale US-05, and want to cold crash the wort from around 30 degrees to about 21 degrees as quickly as possible, and then pitch the yeast.
However, by using beer mode, my chest freezer only cools to about 15 degrees. This does not have the desired effect of quickly reducing the temperature. I would be happier if the freezer temperature cooled a lot more.
How can I achieve this? I thought about using fridge mode but do not want to set it low and forget about it, and ending up with a frozen wort! If I adjust any of the settings, could it have any unintended consequences?
